${\mathrm{AlF}}_{3}$ is soluble in $\mathrm{HF}$ only in presence of $\mathrm{KF}$. It is due to the formation of
The hybridization of atomic orbitals of nitrogen in ${\mathrm{NO}}_{2}^{+}, {\mathrm{NO}}_{3}^{-}$ and ${\mathrm{NH}}_{4}^{+}$ respectively are
When copper is heated with conc. $HN{O}_{3}$ it produces:
In which of the following options the order of arrangement does not agree with the variation of property indicated against it?
The product obtained as a result of a reaction of nitrogen with $Ca{C}_{2}$ is:
The correct geometry and hybridization for ${\mathrm{XeF}}_{4}$ are
Which of the following pairs of ions is isoelectronic and isostructural?

The correct bond order in the following species is:
In which of the following pairs, both the species are not isostructural?
Because of lanthanoid contraction, which of the following pairs of elements have nearly the same atomic radii? (Number in the parenthesis are atomic numbers).
Which of the statement given below is incorrect?
Spin only magnetic moment $2.84 \mathrm{BM}$ is given by: (Atomic Number of $\mathrm{Ni}=28,\mathrm{Ti}=22,\mathrm{Cr}=24,\mathrm{Co}=27$)
The variation of the boiling points of the hydrogen halides is in the order $HF>HI>HBr>HCl$ . Which of the following option explains the higher boiling point of hydrogen fluoride?
Which of the following options represents the correct bond order?
The sum of coordination number and oxidation number of metal M in the complex $[M{(en)}_{2}({C}_{2}{O}_{4})]Cl$ (Where en is ethylenediamine) is:
The formation of the oxide ion, ${O}^{2-}(g)$ , from oxygen atom requires first an exothermic and then an endothermic step as shown in below: $O(g)+{e}^{-}\longrightarrow {O}^{-}(g) ; {\Delta }_{f}{H}^{\ominus }=-141 kJ mo{l}^{-1}$ ${O}^{-}(g)+{e}^{-}\longrightarrow {O}^{2-} (g) ; {\Delta }_{f}{H}^{\ominus }=+780 kJ mo{l}^{-1}$ Thus process of formation of ${O}^{2-}$ in gas phase is unfavourable though ${O}^{2-}$ is isoelectronic with neon. It is due to the fact that,
Decreasing order of stability of ${O}_{2}, {O}_{2}^{-}, {O}_{2}^{+}$ and ${O}_{2}^{2-}$ is:
